TABLE X.—Results Application of Heat to the axes of Mimosa pudica
—continued.

No. of
Experi-
ment.
Result.
33 Application as in No. 29, the points of the forceps almost touching the pulvinus of
the leaf next below.— Slow action in first two leaves above; no action below.
34 Application as in No. 29. —Very long pause; action in the primary pulvinus of leaf
next above; very long pause; commencing action in the pinnæ of the first
leaf, and action in primary pulvinus of the next leaf above; pause; action in
the pinna of the second leaf; no action below.
35 Application as in No. 29. —Long pause; action of leaf next above; very long pause;
action in terminal leaf of axis separated by six internodes from the previous
leaf; action in the leaf below the terminal one; pause; action in leaf above that
one which acted first; no further action.
36 Application as in No. 29. —Pause; action in leaf next above; short pause; action in
leaf next below; very long pause; action in primary pulvinus of second leaf
above site of application; long pause; action in its pinnæ; no further result.
37 Forceps very strongly heated. —Almost. immediate action in leaf next below; long
pause; action in primary pulvinus of first leaf above; pause; progressive, cen-
trifugal action in its pinnæ; very long pause; action of the third leaf above
the site of application; partial and slow action in pinnæ of the second leaf
above the site of application; no further result.
38 Application as in No. 29. —Action in leaf next above; action in leaf next below; ac-
tion of the second leaf beneath that (the intermediate leaf was at a rooted node);
action in the first leaf of the axillary shoot of the leaf above the point of appli-
cation; no action in the second leaf above, which was situated at a rooted
node.
39 Application as in No. 29. —Action in all the leaves above the point of application;
no action below.
40 Application as in No. 29. —Action in fourteen leaves on axis and shoots above, the
primary pulvini alone acting in the more distal ones; no action below.
41 Application immediately above the inferior leaf. —Slow, progressive, centrifugal
action in the primary pulvini of all the leaves above; the secondary pulvini and
pinnules only acted in some cases, and in these after long intervals; no action
below.
42 In this experiment the flame of a wax match was applied direct to the axis. —Ac-
tion in four leaves above; no action in the fifth and terminal one; no action
below.
